Data Sheet

Valve station
Type ICF SS 20 and ICF SS 25

A complete range of modern, exible stainless steel components
for Industrial refrigeration

Based on advanced technology the ICF SS valve
station incorporates several functions in one
housing, which can replace a series of
conventional mechanical, electro-mechanical
and electronically operated valves.

This valve station not only provides a number
of advantages in the design phase of a
refrigeration plant but also in the installation,
service and maintenance.

The ICF SS valve stations are designed for low
and high pressure refrigerants and can be used
in pumped liquid lines, liquid injection lines
and hot gas lines.

Supplied as a complete assembly, it is fully
tested at high pressure and its functions are
tested under factory controlled conditions.

One code number equals one application
solution.

Valve station, Type ICF SS 20 and ICF SS 25

Features

• Designed for industrial refrigeration applications for a maximum working pressure of 52 bar / 754 psig

• Applicable to HCFC, non ammable HFC, R717 (Ammonia) and R744 (CO2). The use of ICF SS valve stations with
ammable hydrocarbons is not recommended

• Direct weld connections (No leaks through anges)

• Stainless steel valve housing and function modules

• Low weight and compact design

• V-port regulating cones on the control modules ensure optimum regulating accuracy particularly at part load

• Modular Concept

◦ Each housing is available with butt-weld DIN connections in several sizes. Valve service is performed by

replacing the function module

• Side ports for the connection of pressure gauges, transmitters, sight glasses, service valve etc

• UL approved

 NOTE:

For specic identication of the dierent codes and ow capacity (Kv) please refer to ordering section.

Examples of application:

Liquid feed line

A valve combination for a ooded evaporator operating on/o from a thermostat and with electric defrost is
required. Manual override of the solenoid valve is requested. Common ICF SS congurations for this kind of
application is shown here:

Refrigerants

Applicable to HCFC, non ammable HFC, R717 (Ammonia) and R744 (CO2). The use of ICF SS valve stations with
ammable hydrocarbons is not recommended.

New refrigerants

Danfoss products are continually evaluated for use with new refrigerants depending on market requirements.

When a refrigerant is approved for use by Danfoss, it is added to the relevant portfolio, and the R number of the
refrigerant (e.g. R513A) will be added to the technical data of the code number. Therefore, products for specic
refrigerants are best checked at store.danfoss.com/en/, or by contacting your local Danfoss representative.
